A strong answer should explain explain that the mechanism of inheritance and variation was not known when darwin published his theory using the context of Theory of evolution (biology only). This supports the approved learning objective: Explain that the mechanism of inheritance and variation was not known when Darwin published his theory. It belongs to Theory of evolution (biology only) within The development of understanding of genetics and evolution, so the explanation must stay inside that curriculum boundary. Alternative answers are weaker if they move away from Theory of evolution (biology only) or the named objective.
